FAQ

Are these shipping bags waterproof?

It depends. Our classic poly mailing bags are made from highly durable LDPE foil, while our more eco-friendly alternatives are made from waterproof bioplastic. This material is great to serve as an additional layer of protection to prevent your box from rain, water and snow. Our paper-based shipping bags are water-resistant. They can take a bit of rain in transit.

How can I design my own mailing bags?

The process starts with the configurator on each product page. Here, you can select the size and quantity you’re after. You will then be taken to our online 3D editor. 

In the editor, you can get creative and design your own packaging in 3D. You can see how different materials and printing options look. Add logos or select templates.

Alternatively, you design on a dieline and upload your own designs.

Next, just hit add to cart and check out.

What are some common uses for mailing bags?

Mailing bags can be used as protective packaging and a shipping solution on their own. Soft goods (e.g., clothing & accessories) and printed material (e.g., magazines) can be shipped using just postal bags. They are a favourite among fashion brands. They are also great for protecting mailer boxes from damage, rain and other elements.
